1. Detailed explanation of the models and parameters of Seven Star Huachuang flow sensors
The core information of the models and parameters of Seven Star Huachuang flow sensors has been summarized as follows, covering the main types such as throttling and heating, and specific parameters include key indicators such as range, accuracy, and applicable cylindrical vertical pin quality. 1. Throttle flow sensor 1.1 D07-23FM/D07-23F This analog range mass flow controller (MFC) and mass flow meter (MFM) belong to throttling products, which are characterized by not being inaccurate due to temperature and pressure fluctuations, good repeatability, automatic measurement and control, and a wide working pressure range. Excellent pressure resistance, using rubber sealing and analog circuits, using DB15 electrical plugs and international standard mechanical connectors, with E certification. It can be used to measure and control various gases, and is widely used in industries such as electronic process equipment and vacuum coating. 1.2 D07-9EM/ZM covers a range of 20, 30, 50, 100, 150, 200, and 250 SLM, with an accuracy of ± 2% F.S, a linear range of ± 0.5-2% F.S, a repeatability of ± 0.2% F.S, and a response time of 1-4 seconds. 1.3 The range of D07-7BM/ZM includes

10、20、30SLM， The accuracy is ± 1% F.S, the linearity is ± 0.5-1% F.S, and the repeatability is ± 0.2% F.S. 1.6 D07-19 is made of stainless steel with an accuracy level of 0.2. It is suitable for gas media and has an electronic style with digital display. The converter is integrated and has a pressure range of low pressure (working pressure 1Mpa). The flow rate measurement range covers 0-5, 10, 20, 30, 50, 100, 200, 300, 500 SCCMkg/h, and the temperature range is medium temperature (working temperature 5-45 ℃). 2. Other models of flow sensors 2.1 CS200-D has a measurement range of 0-200 SCCM and is suitable for gas media. The specifications include G1/4-8mm connectors. 2.2 CS330 is a high-end digital thermal product with a maximum flow rate of up to 200 SLM nitrogen gas and supports digital/analog control modes. Adopting a new all metal sealing structure, a high flow and low pressure loss electromagnetic control valve, and advanced polishing technology, it can measure various gases. It has the advantages of high accuracy and fast response, and supports DeviceNet and RS485 communication protocols. In terms of technical parameters, the valve type is normally closed, the flow specifications (N2) are 100 and 200 SLM, the accuracy is ± 1.0% S.P. when the flow rate is greater than 35% F.S., ± 0.35% F.S. when it is ≤ 35% F.S., the linearity is ± 0.5% F.S., the repeatability is ± 0.2% F.S., the response time is ≤ 1 second, and the working pressure difference range is 100-300 KPa when it is 50 ＜ F ≤ 100SLM, and 200-300 KPa when it is 100 ＜ F ≤ 200SLM.
